Superhuman

Superhuman is an AI-native productivity platform built around a fast email client (Mail), collaborative documents (Docs, formerly Coda), a proactive AI assistant (Superhuman Go), the Grammarly writing assistant, Calendar, and Databases. Following the combination of Superhuman, Grammarly, and Coda, the company operates a developer platform: first-party Model Context Protocol (MCP) servers for Mail and Docs that let AI clients such as Claude, ChatGPT, and Cursor act on a user's mail and document context; a Superhuman Agents SDK and Docs SDK for extending the surface; and REST APIs for Docs, Docs Admin, Grammarly, and audit logs. Security posture is published through a SafeBase trust center with SOC 2 Type 2 and ISO/IEC 27001/27017/27018/27701 attestations, and service health is tracked on a public Atlassian status page.

Superhuman is profiled on the APIs.io network. Tagged areas include Company, Email, Productivity, Artificial Intelligence, and Email Client.

Superhuman’s developer surface includes documentation, API reference, engineering blog, support, pricing, signup flow, and 11 more developer resources.
